Comparison of satellite-retrieved sea-surface temperatures with drifter and ship-borne measurements
(NATO. SACLANTCEN, 1996/01)Sea-surface temperatures (SST) retrieved from satellite imagery are compared with in-situ measured data. The satellite data are from the Advanced Very High Resolution Radiometer (AVHRR) of the series of NOAA satellites, ... -
Inversion of broad-band multitone acoustic data from the YELLOW SHARK summer experiment
(NATO. SACLANTCEN, 1997/09)Integral geoacoustic properties of the sea bottom were determined from full-field inversion of broad-band, waterborne, acoustic propagation data. The data were obtained during the YELLOW SHARK 94 experiment along a 15-km ... -
MAKE-MAP and MEDMAP: two programs for plotting maps of the Mediterranean Sea
(NATO. SACLANTCEN, 1988/06)Two FORTRAN programs MAKE_MAP and MEDMAP are described which, when used together, will plot maps of all or any portion of the Mediterranean Sea. Examples are given which show the high degree of detail provided by the 2' ... -
Mapping ocean sediments by RBF networks
(NATO. SACLANTCEN, 1992/09)Interpolation of sparse measurements of ocean-sediment properties by generalized radial basis function (RBF) networks is proposed. An RBF -
Measurements for satellite validation made from the RV Alliance during October and November 1991
(NATO. SACLANTCEN, 1993/08)Measurements of sea-surface temperature, surface meteorology and atmospheric profiles were taken from the RV Alliance between 1 October -
Mixed layer deepening and variability in the upperlayers if the central western Mediterranean, MILEX-82: final report
(NATO. SACLANTCEN, 1988/10)The 1982 Mixed-Layer Experiment (MILEX-82) is described in detail and the data are presented in ways designed to illustrate the spatial and temporal variability of the surface and deeper layers of the central western ... -
Observations of Mediterranean flow into the Black Sea
(NATO. SACLANTCEN, 1997/10)Mediterranean Sea water inflow into the Black Sea is investigated using acoustic and oceanographic data obtained in the Black Sea exit region. The path of Mediterranean water and the resulting spreading on the continental ... -
Oceanographic measurements of the West Black Sea: November 26 to December 14, 1995
(NATO. SACLANTCEN, 1998/06)Mediterranean water inflow into the Black Sea is investigated using acoustic and oceanographic data obtained in the Black Sea exit region. Temporal and spatial variability in the flow and their relation to atmospheric and ... -
On the predictability of subsurface sound speed from satellite-measured sea-surface temperature in the Mediterranean
(NATO. SACLANTCEN, 1996/01)The report investigates the extent to which subsurface sound speed may be determined from satellitemeasured -
Passive ranging with the SNAP model: a performance study
(NATO. SACLANTCEN, 1987/07)A passive ranging technique which uses SNAP, the SACLANT Centre's normal-mode model, is studied. An examination is made of the sensitivity of the technique to errors in the assumed sound -
Performance assessment of propagation models in AESS-6.0
(NATO. SACLANTCEN, 1999/08)A set of AESS propagation-loss predictions has been generated for typical operational scenarios in both deep and shallow water, for two sonar frequencies (500 and 3500 Hz) and for several source-receiver combinations. ... -
Planning tools for maritime operations
(NATO. SACLANTCEN, 1996/06)The Commander Allied Naval Forces Southern Europe (COMNAVSOUTH) tasked SACLANT Undersea Research Centre to conduct a study to optimize the employment of limited ASW assets in the protection of shipping in the Western ... -
Sound attenuation between 200 and 10,000 cps measured along single paths
(NATO. SACLANTCEN, 1965/09)In the deep Mediterranean basins, the water is perfectly isothermal below 400 m, and the deep refracted ray gives clear signals up to 40 km, with a spreading loss free from any frequency-dependent effect. Exploiting this ... -
The characterization of a range-dependent environment using towed horizontal array data from the MAPEX 2000 experiment
(NATO. SACLANTCEN, 2002/11)The characterization of ocean environments using geoacoustic inversion techniques has received a -
The effect of thermohaline variability on the exchange through Mediterranean straits
(NATO. SACLANTCEN, 1989/05)exchanges through straits. The primary assumption is that the exchange is determined by tlle pressure force created by the differing weights of tlle water columns on either side of the sill and by the continuity of mass ... -
Wave theory modelling of convergence zone propagation in the ocean
(NATO. SACLANTCEN, 1987/06)Improved numerical techniques together with continual advances in computer technology have now
